Bug#782702: header files installed directly in /usr/include

[Vincent Nivoliers]

Package:  libalglib-dev
Version:  3.8.2-3
Severity: minor
Tags:     patch

When the package is installed, the header files are installed directly 
in /usr/include. This creates for instance a file 
"/usr/include/statistics.h".

I suggest to create a folder "libalglib" in /usr/include to install the 
headers there. This is the behaviour found in other distributions like 
for instance archlinux.

Although I am no debian packaging specialist, downloading the source 
package and modifying it as follows yields the desired behaviour when 
the package is built and installed.
