Description of new algorithm for step by step LeBailFit refinement is inadequate

[Alex Buts]

Every algorithm which appears in GUI should have a Wiki page and I have found nothing for the one created fir the ticket #8089. Not sure if wikimaker runs for Python code but even if it does, existing document string is inadequate. "Copy from Part 1 LeBailFit" is not a description

1) Algorithm description should contain brief purpose, list of parameters, acceptable parameters values, what is expected to obtain as the result.

2) User should be able to find the description of the columns in log table produced by the workflow algorithm and I was not able to find any.

3) The Optimization part of the LeBailFit description (http://www.mantidproject.org/LeBailFit#Optimization) has broken sentences. E.g. The experience to use non-linear minimizes such as Simplex or ... This also should be fixed for this ticket.

Hint to verify the ticket

The goal of this ticket is to add wiki page to algorithm RefinePowderDiffProfileSeq and correct the wiki page of LeBailFit. So their wiki pages should be checked. And it is also useful to check whether the wikimaker on Jenkins does not complain about these two algorithms.
