First part of dealing with #110. Have defined a Beam & DuchampBeam? class and use these to hold the beam information. FitsHeader? holds the one that we work with, and copies it to Param for use with outputs. Parameters will be taken into account if no header information is present. Still need to add code to deal with the case of neither being present (the beam being EMPTY) and how that affects the integrated flux calculations.

1251	Usage: $0 [OPTION]... [VAR=VALUE]...
1252
1253	To assign environment variables (e.g., CC, CFLAGS...), specify them as
1254	VAR=VALUE. See below for descriptions of some of the useful variables.
1255
1256	Defaults for the options are specified in brackets.
1257
1258	Configuration:
1259	-h, --help display this help and exit
1260	--help=short display options specific to this package
1261	--help=recursive display the short help of all the included packages
1262	-V, --version display version information and exit
1263	-q, --quiet, --silent do not print \`checking ...' messages
1264	--cache-file=FILE cache test results in FILE [disabled]
1265	-C, --config-cache alias for \`--cache-file=config.cache'
1266	-n, --no-create do not create output files

1269	Installation directories:

1272	--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX

1275	By default, \`make install' will install all the files in

1277	an installation prefix other than \`$ac_default_prefix' using \`--prefix',
