Find intervals according to various search criteria.

1 2	findIntervals(tier, pattern = "*", from = -Inf, to = Inf, at = numeric(), stringsAsFactors = FALSE, ...)

`tier`	An `IntervalTier` object.
`pattern`	A regular expression for matching interval labels. Default is `'*'` so that the search finds all intervals within `[from, to]`.
`from`	A numeric, the earliest time from which to search for intervals. Default is `-Inf` so that the search includes the start of `tier`.
`to`	A numeric, the latest time to which to search for intervals. Default is `Inf` so that the search includes the end of `tier`.
`at`	A numeric, an exact time at which to find intervals. Default is `numeric()` so that intervals are searched within `[from, to]`.
`stringsAsFactors`	A logical, default is `FALSE`.
`...`	optional arguments passed to `grep`.

Default behavior of findIntervals is to search for intervals within [from, to]. If the at argument is a non-empty numeric vector, then this default behavior is overridden, and the tier is searched only at the time given by at.

A data.frame whose rows correspond to the intervals found according to the search criteria, and whose columns are: $Index, $StartTime, $EndTime, $Label,
