Include or exclude journal entries

It is now possible to exclude some journal entries from all computations, more or less like when showing or hiding different layers in computer graphics programs.

Since LearnDoubleEntry.org is a learning platform, this opens up the possibility to test different scenarios, or simply to prepare a journal entry to ask somebody help for.

Excluded journal entries are listed in the journal in gray with a line-through decoration. The amounts of the postings are not considered in the ledger, in the trial balance and in the financial statement.
