[teqc] qc changes for the next teqc release

All,

There are some changes in the qc reporting of the next teqc release,
which I'll summarize below.  The teqc with these changes and additions
is currently undergoing a few days of burn-in at the UNAVCO Facility.
Assuming all goes well (and one day of tests had no problems), we'll
be set for the next official release next week.

--------

* missing epochs in ASCII time plot when qc lite (no nav messages or
no position found); this is explained in more detail in the previous
email http://ls.unavco.org/pipermail/teqc/2009/000801.html

--------

* bug when repeated data epochs fixed, and new "Epochs repeated"
line; this is explained in more detail in the previous email
http://ls.unavco.org/pipermail/teqc/2009/000802.html

--------

* activation of a '+' indicator on the '-dn' and '+dn' qc full lines
when there are complete observations below the elevation mask
(= 10 degrees by default).  This is best seen by example:

[2310] teqc +qcq eliz0570.09o 2> /dev/null | grep "^[-+]dn"
-dn|  1111    1  + + 1   11     ++       +       1        1211 11+1  ++ 1+  |-dn
+dn|1222221  1111121111 1221 111 1 1121 1111211111    1 12222c121111   11111|+dn

The '+' symbols on the -dn line are telling us that there is some
complete usable data below 10 degrees.  Raising the mask to 20 degrees:

[2311] teqc -set_mask 20 +qcq eliz0570.09o 2> /dev/null | grep "^[-+]dn"
-dn|   + +       +++          + ++ +++  +++ +             1111   +   ++  ++ |-dn
+dn|                1   111   1    1            1        1211c11 1     1    |+dn

and then lowering the mask:

[2312] teqc -set_mask 8 +qcq eliz0570.09o 2> /dev/null | grep "^[-+]dn"
-dn| 12111    1  +   1   111   1+   11    1      1        1211 11 1  ++ 11  |-dn
+dn|1333231  221113211112221112111 1221113213111111  12112222c122211  111211|+dn

Still some '+' at 8 degrees, so:

[2313] teqc -set_mask 7 +qcq eliz0570.09o 2> /dev/null | grep "^[-+]dn"
-dn|1322121   1  +   1   111   1+   11   11 1    1        1211 1211  ++ 11 1|-dn
+dn|34432411 221113311112221113111 1222113223211111  12212232c123311  111322|+dn

still some '+' at 7 degrees, so:

[2314] teqc -set_mask 6 +qcq eliz0570.09o 2> /dev/null | grep "^[-+]dn"
-dn|1332221   1      11  111   1    11  11111    1        1211 1221     11 1|-dn
+dn|34444421 221113321212222113121 1232223223211112 112312232c233321 1111332|+dn

Hint: this _might_ mean that the elevation mask of the receiver was set to
5 or 6 degrees.  Some of you might want to exeriment with this and report
back if this approach is a good diagnostic for determining the receiver's
cutoff angle.

Background: This happened to be lurking the the code for the last 13 years!
I just never activated its display in the -/+dn lines.

I could add a line reporting the number of complete observations found
below the cutoff mask in the report if people are interested in
actual numbers.

--------

* new 'Missed obs' line just before 'Deleted obs': Recall that
deleted observations are those SV epochs with incomplete dual-frequency
data above the elevation mask, but have some data for the epoch.
'Deleted obs' are those SV epochs for which there is some other
SV data for the epoch, but there are one or more SVs that should be
above the elevation mask but have no data.  (I.e. thus this does not
include observations from epochs that are entirely missing.)

--------

* when windowing, new count lines complementing the alternate SWN
summary line:  This is perhaps best seen by a few examples:
