Function to find line representing maximum lake Width
Description
Maximum lake width is defined as the maximum in lake distance that is
perpendicular to the maximum lake length. As no definition specifies whether
or not the maximum lake width should intersect the line of maximum legnth,
this function assumes that it does not, but may be forced to find the maximum
width line the is perpendicular to and intersects with the maximum lake
length line. This function calculates the equation of the perpendicular line
and repeats that line pointDens
number of times and returns the longest
of those lines.
Usage
1  lakeMaxWidth(inLakeMorpho, pointDens, intersect = FALSE, addLine = T)

Arguments
inLakeMorpho 
An object of 
pointDens 
Number of points to place equidistant along the

intersect 
Boolean to force max width to intersect the max length line. for many lakes this will return the same line. 
addLine 
Boolean to determine if the selected max length line should be added to the inLakeMorpho object. Defaults to True 
Value
Returns a numeric value indicating the length of the longest line perpndicular to the maximum length line.
