Trim sprof stack information by top level or by node.

1	trimstacks(sprof, level, trimnode)

`sprof`	a `sprof` data structure, if available, or a `stacks$nodes` information.
`level`	Level to cut off.
`trimnode`	A node considered end of scaffold. Entries up to and including this node are trimmed. Nodes can be marked as index, or as node name.)

The level information is evaluated first, and then the node information is evaluated.

A data structure corresponding to stacks$nodes, with the trimmed parts cut off. This may contain NULL entries.

 trimmed <- trimstacks(sprof01lm, trimnode="summary")
sprof01lm$stacks$nodes <- trimmed  #now the refereces are update, and graphs will work
sprof02lm <- updateRprof(sprof01lm) #now the info is updated, and summeries will be consistent.
