9 ** Function: check_install
10 ** Description: Checks to see if WMS is installed
11 ** Output:
12 ** x_return_status
13 ** return status indicating success, error, unexpected error
14 ** x_msg_count
15 ** number of messages in message list
16 ** x_msg_data
17 ** if the number of messages in message list is 1, contains
18 ** message text
19 ** Input:
20 ** p_organization_id
21 ** -specific organization to be checked if WMS enabled.
22 **
23 ** -if NULL, the check is just made at site level
24 ** and not for any specific organization.This is more relaxed than
25 ** passing a specific organization.
26 ** Returns:
27 ** TRUE if WMS installed, else FALSE
28 **
29 ** Please use return value to determine if WMS is installed or not.
30 ** Do not use x_return_status for this purpose as
31 ** . x_return_status could be success and yet WMS not be installed.
32 ** . x_return_status is set to error when an error(such as SQL error)
33 ** occurs.
