an MCA parameter's value came from. Note that the actual value of the
parameter is irrelevant. For example, if a value was specified in an
MCA parameter file that happened to have the same defaultvalue that
was specified when the parameter was registered, the returned location
will indicate that the value was set from the file.
Possible answers:
* '''MCA_BASE_PARAM_SOURCE_DEFAULT:''' no user-specified values were
found, so the default value was used
* '''MCA_BASE_PARAM_SOURCE_ENV:''' the value came from the
environment (which also means the mpirun/orterun command line!)
* '''MCA_BASE_PARAM_SOURCE_FILE:''' the value came a file (or the
Windows registry)
* '''MCA_BASE_PARAM_SOURCE_KEYVAL:''' the value came from a keyval
(can currently never happen)
* '''MCA_BASE_PARAM_SOURCE_OVERRIDE:''' the value came from an MCA
param API "set" function
