New feature: GNSS-SDR now reads the IFEN NSR 2bit sample file format. The GNSS-SDR receiver can now be used with the SX-NSR scientific navigation front-end receiver using its native .stream binary captures.
More information of this high-end front-end can be found here: http://www.ifen.com/products/sx-scientific-gnss-solutions/nsr-software-receiver.html git-svn-id: https://svn.code.sf.net/p/gnss-sdr/code/trunk@421 64b25241-fba3-4117-9849-534c7e92360d
