A reader for hledger's journal file format
(<http://hledger.org/MANUAL.html#the-journal-file>). hledger's journal
format is a compatible subset of c++ ledger's
(<http://ledger-cli.org/3.0/doc/ledger3.html#Journal-Format>), so this
reader should handle many ledger files as well. Example:
@
2012\/3\/24 gift
expenses:gifts $10
assets:cash
@
Journal format supports the include directive which can read files in
other formats, so the other file format readers need to be importable
here. Some low-level journal syntax parsers which those readers also
use are therefore defined separately in Hledger.Read.Common, avoiding
import cycles.
