Support of Wavelet/Cosine Packet Funcrion
DESCRIPTION:
Compute the support of a wavelet or cosine packet function.

This function is generic (see Methods); method functions can be written to handle specific classes of data. Classes which already have methods for this function include:

cosine.packet, cosine.packet.2d, wavelet.packet, wavelet.packet.2d.

USAGE: 
support(x)
REQUIRED ARGUMENTS:
x:
an object of class cosine.packet, cosine.packet.2d, wavelet.packet or wavelet.packet.2d.
VALUE:
for 1D objects, returns a vector of length two, representing an interval; for 2D objects, returns a 2 by 2 matrix.
