newwarpDEDataSet: Initialize an object of class 'warpDEDataSet'
In strayMat/lineageDE: Differentially expressed genes in cell lineages

Constructs a warpDEDataSet object. Additional helper methods for manipulating warpDEDataSet objects are also described below.

1	newwarpDEDataSet(counts, t, w, ...)

`counts`	matrix. An `n` by `m` numeric matrix or data frame giving the filtered, normalized RNA counts. In rows are the genes and in columns are the cells. It should contain the names of the cells and the genes in `colnames(counts)` and `rownames(counts)`.
`t`	matrix. An `m` by 2 numeric matrix denoting each cell's reconstructed ordering position or pseudotime for the two lineages to compare.
`w`	matrix. An `m` by 2 numeric matrix denoting each cell's probability to belonng to each lineage. The probability should be convex, i.e The sum of the columns shoudl add up to 1.
