1. A fuel injector, comprising: a first tube, having first and second opposing ends, which is supplied with fuel and connectable with a vessel at the second end thereof; andplurality of second tubes disposed within the first tube, each of the plurality of second tubes being supplied with air and having:sidewalls defining injection holes through which the fuel enters each of the plurality of second tubes to mix with the air, andan outlet end of the sidewalls corresponding to the second end of the first tube,wherein a main flowpath is defined through the vessel from an upstream location to a downstream location and a number of the injection holes of each one of the plurality of second tubes decreases along a direction of flow along the flowpath. 2. The fuel injector according to claim 1, wherein a number of the injection holes of each one of the plurality of second tubes remains substantially uniform along a direction perpendicular to a direction of flow along the flowpath. 3. The fuel injector according to claim 1, wherein the decrease in the number of injection holes is incremental. 4. The fuel injector according to claim 3, wherein a number of the ones of the plurality of second tubes having an intermediate number of injection holes is greater than numbers of the ones of the plurality of second tubes having high and low numbers of injection holes. 5. A fuel injector, comprising: a first tube, having first and second opposing ends, which is supplied with fuel; anda plurality of second tubes disposed within the first tube, each of the plurality of second tubes being supplied with air and having sidewalls defining injection holes through which the fuel enters each of the plurality of second tubes to mix with the air, and an outlet end opening through the second end of the first tube,a number of the injection holes of each one of the plurality of second tubes being different from a number of the injection holes of at least another one of the plurality of second tubes. 6. The fuel injector according to claim 5, wherein a number of the injection holes of each one of the plurality of second tubes remains substantially uniform along a direction perpendicular to a direction of flow along the flowpath. 7. The fuel injector according to claim 5, wherein the first tube is connectable with a vessel at the outlet end thereof, a main flowpath being defined through the vessel from an upstream location to a downstream location. 8. The fuel injector according to claim 7, wherein a number of the injection holes of each one of the plurality of second tubes decreases along a direction of flow along the flowpath. 9. The fuel injector according to claim 8, wherein the decrease in the number of injection holes is incremental. 10. The fuel injector according to claim 9, wherein a number of the ones of the plurality of second tubes having an intermediate number of injection holes is greater than numbers of the ones of the plurality of second tubes having high and low numbers of injection holes. 11. A gas turbine engine, comprising: a vessel having a liner defining an interior through which a main flowpath is defined from an upstream location to a downstream location; anda fuel injector, including a first tube having first and second opposing ends, which is supplied with fuel and connectable with the vessel liner and a plurality of second tubes disposed within the first tube, each of the plurality of second tubes being supplied with air and having sidewalls defining injection holes through which the fuel enters each of the plurality of second tubes to mix with the air, and an outlet end opening into the vessel interior,a number of the injection holes of each one of the plurality of second tubes being different from a number of the injection holes of at least another one of the plurality of second tubes. 12. The gas turbine engine according to claim 11, wherein a number of the injection holes of each one of the plurality of second tubes decreases along a direction of flow along the flowpath.
