Add availability filter

[acavelan]

Add the possibility to deploy interventions with a minimum and / or maximum host availability. This is only useful when heterogeneity is used. This may be used for example to simulate the deployment of interventions to remote areas where hosts are more exposed to bites.

Heterogeneity in human-to-mosquito availability can be enabled in the vector model by specifying a distribution and coefficient of variation (or variance) for each species. For example:
<availability distr="lognormal" CV="2"/>
or
<availability distr="gamma" variance="2"/>

OpenMalaria will pre-compute percentiles by sampling the distribution made of the sum of the availability distribution for each species. Only the raw availability will be considered here, this excludes reduction in availability due to age or interventions.

The deployment of human interventions (timed, cumulative or continuous) now allows a minimum and / or a maximum availability percentile, as follows:

    <interventions name="GVI example">
        <human>
            <component id="GVI_example">
                <GVI>
                    <decay function="exponential" L="3y"/>
                    <anophelesParams mosquito="gambiae_ss">
                        <deterrency value="0.7696"/>
                        <postprandialKillingEffect value="0.0544"/>
                    </anophelesParams>
                    <anophelesParams mosquito="funestus">
                        <deterrency value="0.7696"/>
                        <postprandialKillingEffect value="0.0544"/>
                    </anophelesParams>
                    <anophelesParams mosquito="arabiensis">
                        <deterrency value="0.7696"/>
                        <postprandialKillingEffect value="0.0544"/>
                    </anophelesParams>
                </GVI>
            </component>

            <deployment name="GVI_example">
                <component id="GVI_example"/>
               <timed>
                    <deploy coverage="0.8" maxAge="95" minAge="0" minAvailability="50" maxAvailability="100" time="2005-01-01"/> 
                </timed>
            </deployment>
        </human>
    </interventions>

Only hosts within the availability percentile range will be considered. If not specified, the range will be 0-100%. Note that 100% is equivalent for infinity.
