=head3 buildreport (note originally written only for xdsh but
now supports rinv also)
This routine will take the input template and compare against
the output of the dsh command and build a report of the differences.
Read a nodes worth of data from the dsh command
Call compareoutput- compares the dsh to the template
Get the template and nodename returned from compareoutput and build hash
Call writereport to take the hash and write the report to the output file
Cleanup
Input (report file, file containing dsh run,template file,template count
whether to remove the generated templates, original dsh node list,
ignorefirsttemplate,exactmatch)
If exactmatch is chosen, a diff is done against the template and the output.
If not exactmatch, then each record (line) in the template must be
checked against the node's output to determine, if it exists.
