Store gene parameters in data.frame rather than separate vectors. Forces them
to be same length and allows more independence between gene parameters and
nGenes. Checking for differences between the number of gene parameters and
nGenes, and sampling if necessary, is now done in `lun2Simulate` rather than
`validObject`. The same is true for nCells and lib.sizes.

Make it clear which are added by Splatter

Drawing quantiles in violins was causing an error

No gives the number of rows in the original counts

Adjust point size

For compatibility with pseudo-counts

Remove cell component

Decided it was unnecessary

* Winsorize means
* Only high outliers
* Scale edgeR dispersion

Fix bug that meant non-linear path factors weren't stored in output of
splatSimulatePaths

* Bump R version to 3.4
* Add row, col names to matrices

* Add locfit to NAMESPACE
* Add return values to logistic, showPP documentation
* Delete commented mergeParams function
* Switch to aes_string in compareSCESets
* Add examples to getParam, setParam
* Adjust line lengths
* Adjust indentation

The last SCESets was been added multiple times
instead of adding each one onces.

Fixes #4

Make it clearer what is the package and what is the simulation

Validity method was set to SimpleParams

Not great, but will do for now
