**PURPOSE** --
Create USCs (User Specified Constraints).

**DEVELOPER** --
Bill Workman

**KEY** --
args = a list containing the argumants from the command line.
queryOptions = a dictionary conaining optional db query parameters.
processOptions = a dictionary containing options such as listonly.
required_args = a dictionary of required arguments.
uscOptions = a dictionary containing USC specification options.
usc_name = Name of USC (see the assist relation usc for examples).
usc_keyword_args = a dictionary of USC specification options.
visitList = a list of visits obtained either from the command line
or a database query.
windowList = a list of dictionaries containing start and end times.

**CODE ALGORITHM** --
1. If no parameters, then print documentation string and exit.
2. Define options and parameters.
3. Set variables from required_args and uscOptions.
4. If visit list is defined use it, otherwise look it up in
the database.
5. If not running in list_only mode, use visit_util.apply_usc
to write the USC's into the database. If running in
list_only mode, print the visit list.

**NOTES** --
1. To create a USC for given visit(s), an example would be:
do create_uscs LRP_GTO_STIS 1999.001:00:00:00 2000.274:00:00:00 -visits="0756601"
2. To create USCs for a range of visits given by a database search,
an example would be (it is suggested to also include the -list_only option
to ensure the database changes proceed as intended):
do create_uscs LRP_GTO_STIS 1999.001:00:00:00 2000.274:00:00:00
-other_qualifiers="and (sut.sunit_id in (select sunit_id from usc where
sunit_id="0756601"))"
Note that a visit's status must be pi, implementation, or scheduling in order
for the database search capability to find a given visit.

Create USCs.

Usage:
do create_uscs usc_name window1_start window1_end
[[window2_start window2_end]...] [-options]

usc_name is the name of the USC to be inserted into assist relation
usc. It must be 50 characters or less in all caps.

window_start and window_end are the start and end times of the window
in SOGS format.

-options are one or more of:

Visit list DB query options (to define the DB search parameters):
-prime
-parallel
-internal
-pure_parallel
-visits= "01234v1 01234v2 01234v3 ..."
-si_modes= "stis_ccd stis_fuv_mama stis_nuv_mama wfpc2 fgs
nic1 nic2 nic3 acs_hrc acs_wfc acs_sbc"
-type= "GO GTO ENG SM..."
-cycle=
OR -min_cycle=
and/or -max_cycle=
-other_qualifiers= "any valid subquery of the form:"
"and (sut.sunit_id in (select sunit_id from ... where ...))"
OR "and (cp.prop_id in (select prop_id from ... where ...))"

USC specification Options:
-usc_mode= "combine" (default) | "override"
-usc_value= (default=1.0)
-usc_comment= "explanatory text" (default="No comment provided.")
-exclude_usc (To define the actual USC inserted into the DB to be
the logical complement of the window defined on the
command line.)
-list_only (When used, function only displays the list of visits
based on query options; USC's are not created.)

Verbose output Options:
-verbose
