Assigns genes to epochs

assign_epochs(
  expDat,
  dynRes,
  method = "active_expression",
  pThresh_dyn = 0.05,
  pThresh_DE = 0.05,
  active_thresh = 0.33,
  toScale = FALSE,
  forceGenes = TRUE
)

`expDat`	genes-by-cells expression matrix
`dynRes`	individual path result of running define_epochs
`method`	method of assigning epoch genes, either "active_expression" (looks for active expression in epoch) or "DE" (looks for differentially expressed genes per epoch)
`pThresh_dyn`	pval threshold if gene is dynamically expressed
`pThresh_DE`	pval if gene is differentially expressed. Ignored if method is active_expression.
`active_thresh`	value between 0 and 1. Percent threshold to define activity
`toScale`	whether or not to scale the data
`forceGenes`	whether or not to rescue orphan dyanmic genes, forcing assignment into epoch with max expression.
