## Plot the distribution of matched alignments.

### Description

Given a `Axt` alignment, plot a heatmap showing the percentage of each matched alignments.

### Usage

      matchDistribution(x, size=10000, title=NULL)

### Arguments

`x` | `Axt` object.
`size` | `integer`(1): the number of alignments to use. By default, it is 10000.
`title` | `character`(1): the customised title for the plot.

By default, if there are more than 10,000 alignments, 10,000 alignments will be sampled and calculated for the distribution for speed purposes.
