Missing description for flux command wait-for-input

[maipet]

There is no description for flux-command "wait-for-input" on https://github.com/metafacture/metafacture-documentation/blob/master//flux-commands.md#wait-for-inputs

Added this in the java class org.metafacture.flowcontrol.CloseSuppressor. I've to generate the flux-commands.md let the description appear in it.
