EpivizBpData-class: 'EpivizBpData' objects
In epiviz/epivizr-tmp: R Interface to epiviz web app

Base-pair resolution quantitative data.

This class extends EpivizTrackData-class directly. As such, its object field is constrained to contain a GIntervalTree object. Quantitative data for each genomic position is assumed to be stored in the elementMetadata slot of object.

: .checkColumns(columns): Checks argument columns is a subset of names(mcols(object)).
: .getColumns(): Returns names(mcols(object)).
: plot(): Calls the lineChart method of EpivizDeviceMgr-class with columns as argument.
: getMeasurements(): Returns named character vector. Entries are of format '<name>$<column>'. Vector names are of format '<id>__<column>'.
: parseMeasurement(msId): Parses measurement of format '<id>__<column>'.
: packageData(msId): Get data for msId for rows overlapping curQuery. Returns a list with components: min: min value for data range, max: max value for data range, data: list with slots: bp: genomic location, value: numeric data value.
