Create a new Earley chart parser, that uses grammar to parse texts.

Parameters
grammar:CFGThe grammar used to parse texts.
trace:intThe level of tracing that should be used when parsing a text. 0 will generate no tracing output; and higher numbers will produce more verbose tracing output.
trace_chart_width:intThe default total width reserved for the chart in trace output. The remainder of each line will be used to display edges.
chart_classThe class that should be used to create the charts used by this parser.
