Trio analysis plugin - pedigree

[dridk]

The trio analysis plugin works fine, but possible ways of improvement:

It seems that the pedigree given at import is not taken into account
=>It should pre-set 'roles' (father, mother, index) associated with each sample

In the case where no pedigree was given at import, maybe create a .tfam once the user set 'role' of each sample + ran analysis
=> Like that, no need to re-attribute role each time we want to run a different trio analysis

Maybe add a sort of correspondance between sampleID and 'roles' based on the .tfam file
=> Like that, VQL queries become clearer, like:
WHERE sample['father'].gt=0 AND sample['mother'].gt=0 AND sample['child'].gt=1
(or should be in a specific issue, because related to the whole interface?)
