peakMatch: Function to match peaks across samples
In flowClust: Clustering for Flow Cytometry

Uses the hungarian algorithm to match peaks across samples, one at a time using a template sample.

1	peakMatch(peaks, target.index, max.fill = 1e+12)

`peaks`	is the matrix of peaks in the columns and samples in the rows
`target.index`	is the index of the template sample.
`max.fill`	is the value to substitute for NAs in the distance matrix. Should be very large, but if too large, will overflow and give an incorrect matching
