Modify UpdateInstrumentFromFile to accept Ascii file

[Martyn Gigg]

UpdateInstrumentFromFile currently only accepts RAW & NeXus. Modify it to accept an ASCII file where an additional property specifies to format like so:

spectrum,theta,t0,-,R

or

id,theta,t0,-,R

where the "-" indicates skip this column and the R,theta,phi have special meaning and link to the corresponding detector values. An additional named columns will be attached as detector parameters.

This is required for supporting the VESUVIO work.

Tester: The UpdateInstrumentFromFile algorithm now accepts a ISIS RAW, ISIS NeXus or an ASCII file and should throw an error if given a file of a different type so please check that this occurs.

An example file for this is attached to ticket #6286 where the columns are:

spectrum,theta,t0,l1,l2

Please try different combinations of ignoring columns and check that those not labeled R,theta,phi or skipped get added as instrument parameters. You can do this from python using

det = ws.getDetector(0) # make sure you set the correct wsindex
print det.getDoubleParameter("t0") # Should give a single-element list with the correct value

There is a minor correction required to properly skip lines if they are not columns of numbers as some files may have a header line with text.

[Martyn Gigg]

UpdateInstrumentFromFile can now skip ascii headers. Refs #6285

Changeset: 48b8f33e42be50f80c2bee5772cf76fd4069a8b1

[Martyn Gigg]

Tester: As well as the tests above please alter the file to have a text header and check that it is still read correctly.

The wiki http://www.mantidproject.org/UpdateInstrumentFromFile is not up to date and the properties listed do not correspond to those in the dialog box for the algorithm. In particular, ignore Phi and Ascii Header are missing. These need to be added and explained. Then testing should be easier. Some example ASCII files might be helpful for this.

Update wiki doc for UpdateInstrumentFromFile. Refs #6285

Documentation should be better now.

The error message got from attempting to update from a Nexus File other than ISIS Nexus states that ".nxs" is not a valid file type, yet it works with a .nxs file that is an ISIS Nexus file. A more informative error message is needed and also .nxs is needed in the filetype menu of the browser. I'll make this issue into a separate ticket.
